The Walking Dead cast and producers took Comic-Con like a storm of hungry walkers Friday, with a premiere date announcement (Season 4 bows Sunday, October 13 at 9/8c), a fresh footage-filled trailer, scoop on a sane Rick, a returning Governor and much more. Here are some of the highlights:

NEW SEASON, SAME SCHEDULE |Walking Dead‘s 16-episode fourth season will once again be divided into two chunks, with the aforementioned first half starting in October and the second beginning in February2014.

LIKE FATHER, LIKE SON | So long, deranged Rick. Hello, crazy Carl. “The relationship with Carl is integral to the beginning of this season,” Andrew Lincoln revealed. “Carl turning into a sociopath at the end of last season definitely woke [Rick] up.” As such, you’ll find the perpetual leader “in a completely new place; he’s renounced a lot of his responsibilities for the sake of his children.”

INSANITY ENSUES | The award for Most Vague But Most Awesome Answer goes to showrunner Scott Gimple, whose tease about Season 4 consisted of this: “It’s going to get insane very quickly.” For his part, Lincoln shared: “When we [see the group] in Season 4, there is a whole new community in the prison and an incredible friction between certain characters.”

LIGHTING UP | Does the Governor have survivor’s guilt after his massive killing spree last year? Maybe so, teased portrayer DavidMorrissey. “At the end of last season, he was in a very dark place — but he feels like they betrayed them and that’s just not going to go down with the Governor,” he laughed. “There was a switch in him, and now [this season] we see him dealing with what that switch is; what is it that makes that switch go down?”

A PLACE IN THE PACK | “Tyreese is still trying to find out how he fits in,” relative newbie Chad Coleman shared of his prison import. “What are the rules of engagement for him and how to negotiate his place in this family?” (Take a peek at the promo below for a glimpse at just how ambivalently useful he can be.)

WE HAVE TO GO BACK | In a twist straight out of Lost, Rick last season opted to return to the prison instead of moving his group to Woodbury… But why? “We answer it this season,” teased Lincoln.
